ipa: Release body more carefully when removing nodes (PR 107944)
The code removing function bodies when the last call graph clone of a
node is removed is too aggressive when there are nodes up the
clone_of chain which still need them. Fixed by expanding the check.

* cgraph.cc (cgraph_node::remove): Check whether nodes up the
lcone_of chain also do not need the body.
